Can you give an edible example of a phase change?
Making ice cream and then letting some of it melt are two examples of phase changes.The extreme cold of the ice cream maker causes the liquid cream to give up its heat and turn solid. This freezing phase change is exothermic because energy (heat) comes out of the cream.If you leave a bowl of ice cream on the table in a warm room, the heat energy of the air will enter into the ice cream and it will become liquid. This melting phase change isendothermic.Memory tip:exo - the heat energy exits the cream, which gets colder.endo - the heat energy goes into the ice cream, which gets warmer.
How do you you bring double cream to a boil?
To bring double cream to a boil, heat it gently in a saucepan over medium heat, stirring constantly to prevent burning. Once bubbles start forming around the edges of the cream and it starts steaming, remove it from the heat before it reaches a full boil.
Metal ice-cube tray and a plastic tub of ice cream are sitting in the freezer Why does the ice-cube tray feel colder to touch than the tub of ice cream?
The metal tray has both a higher specific heat (ability to gain or hold heat) and a higher conductivity (ability to transfer heat). So while the ice cream will increase in temperature where you touch it (and hence only absorb a small amount of body heat), the tray can absorb more heat, and transfer it to all of the metal and ice in the tray. (This is also why you can lick a wooden pole in the winter, but not a metal one!)
What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
What has higher specific heat water or lead?
Water has much higher specific heat than lead. All metals have fairly low specific heat values.
How can I prevent scalded cream when making desserts that require heating cream?
To prevent scalded cream when making desserts that require heating cream, it is important to heat the cream slowly and gently over low to medium heat. Stir the cream constantly to distribute the heat evenly and prevent it from scorching. Remove the cream from the heat as soon as it reaches the desired temperature, usually just before it starts to simmer.
How can I use steam to heat heavy cream for making a delicious dessert?
You can use steam to heat heavy cream by placing a heatproof bowl of cream over a pot of simmering water. The steam will gently heat the cream without scorching it, making it perfect for creating a delicious dessert.
Why specific heat is large specific volume?
Specific heat has nothing to do with specific volume.
How do you stop cream from splitting while cooking?
If you mean curdling , you need to heat the cream slowly and not add it to a hot mixture when it is cool. If cream is needed to be added to a hot mixture, slowly heat the cream to mixtures temperature in a separate pot and add it when it is hot.
What is the specific heat of sinter?
Specific heat of sinter

Why does ice cream melt faster in warm water than it does in cold water?
According to thermo-chemistry, warmer substances have higher heat energy. Using qs = CsMsΔTs where qs is heat of the sample, Cs is specific heat capacity of the sample, Ms is mass of the sample, and ΔT is change in temperature of the sample, you can determine the amount of heat energy transferred. Because warm water has more heat energy than cold water, it affects the temperature of the ice cream more, making it melt faster. THis can be seen by rearranging the above formula like this: qs/(CsMs) = ΔTs to find the change in temperature of the ice cream (where the substance is ice cream)
how can you fry ice cream if ice cream melts once we place it in high heat?
The ice-cream needs to be used straight from the freezer... You coat the ice-cream in pancake batter. The batter acts as an insulated barrier against the heat. The batter cooks, while the ice-cream remains intact.
Is ice cream good?
It depends on what kind of ice cream you get and your specific tastes.
How to scald cream effectively for cooking or baking purposes?
To scald cream effectively for cooking or baking, heat it in a saucepan over low to medium heat until small bubbles form around the edges of the cream. Do not let it boil. Remove from heat and use as directed in your recipe.
Is Ultra Heat Treated cream high risk?
Not particularly - ultra heat treated is likely referring to ultra-high heat pasteurization techniques that are designed to kill most pathogenic organisms in the cream. However, you still need to keep the cream chilled and use it by its expiration date.
